Just had a quick play with my moth trap records this morning to see how marked the difference was between results from this summer and last summer given the weather. I looked at the data from April to September (inclusive), having trapped weekly throughout both periods (with one week missed in 2012). 2012 also included one moth night in which George and Paul both brought their traps and therefore, if anything, the 2012 results are higher than they otherwise would have been...
Total trap nights: 2012 = 29, 2013 = 30
Total moths caught: 2012 = 1417, 2013 = 3000
Number of species: 2012 = 209, 2013 = 275
